Comparing our flush sash range: Infinity vs Residence 9

Infinity vs Residence 9

PVCu flush sash windows are designed to replicate the traditional aesthetic of timber windows. When closed, they sit flush in the frame to give a smooth appearance to the exterior of a property. They are regularly used in period property renovations and conservation area properties where tastefully replicating the original window style is essential.

Thanks to modern advancements in technology, today’s PVCu flush sash windows are almost impossible to differentiate, in terms of appearance, from their original timber counterparts. Years of research and design has gone into creating a modern window with a truly classic appearance.

PVCu flush sash windows can be specified with a range of period features to match the architectural era which they are designed to replicate. From Georgian bars and slim sightlines to realistic woodgrain effect finishes and traditionally styled hardware, today’s PVCu flush sash windows provide the classic timber appearance with the low maintenance and outstanding performance of 21st century engineering.

PVCu flush sash windows for trade installers

At Dekko, we supply two collections of PVCu flush sash windows to trade installers across the UK. Both Infinity flush sash windows and Residence 9 flush sash windows are designed to faithfully replicate the appearance of traditional timber windows. They both provide end-users with a wide range of benefits and can be custom designed to suit a selection of different installations.

If you’re a glazing installer, who regularly works on period properties and more traditional buildings, flush sash windows are an essential part of your product portfolio. If you’re more involved in modern property renovations or new-build projects, flush sash windows are becoming an increasingly popular choice with both developers and contemporary homeowners.

The rise in popularity of luxury PVCu flush sash windows

Infinity Flush Sash

There was a time when PVCu was viewed as the most cost-effective option and took a backseat when compared to other window materials. Thanks to new innovations in technology, PVCu windows now rival both aluminium and timber for their status as the premium window material choice.

Both Infinity flush sash windows and Residence 9 windows both provide end-users with a high-end window system which is designed to offer the most luxurious appearance and outstanding performance available today. With increasingly strict regulations on window performance criteria, both systems are perfectly placed to provide decades of excellence for trade glazing installers.
